AI Generated Solution

To solve the problem, we need to convert a galvanometer into an ammeter and a voltmeter. Let's break it down step by step. ### Part (A): Converting Galvanometer to Ammeter of Range 10A 1. **Identify Given Values**: - Resistance of galvanometer, \( R_g = 100 \, \Omega \) - Current through galvanometer, \( I_g = 10^{-3} \, A \) - Desired range of ammeter, \( I = 10 \, A \) ...
